You installed FM via steam, you need to
Verifying game files -> Restarting Steam -> Verifying game files
then try. My friend had this problem, and I found a solution few weeks ago, but now, I can't find it. Sorry, i'll try harder.

-Load Steam
-From the My Games tab, right-click on FM2011 and select Properties from the menu.
-Select the Local files tab and click the Verify integrity of game cache... button.
-Steam will verify the game cache files (GCF's) - this process may take several minutes.
-Once the process is completed, the Check Window will automatically exit.
